As the term physical implies, physical digestion is the"moving" part of digestion, which includes peristalsis, a series of wave-like contractions that move food down your alimentary canal.
Chemical digestion would refer to the chemical reactions that occur during digestion, for example proteins being broken down by protease to form the end product amino acids.
